Identifying citrus limonoids as a potential fusion inhibitor of DENV-2 virus through its in silico study and FTIR analysis.

Unlabelled: Dengue virus type 2 (DENV-2) is an arthropod-borne deadly RNA human pathogen transmitted through the mosquito Aedes. The DENV-2 roots viral infection by facilitating entry with its envelope glycoprotein to the receptor protein Dendritic-cell-specific ICAM3-grabbing non-integrin (DC-SIGN) through membrane fusion. Here, an organizational path is reported for inhibiting the transition due to fusion activation and by blocking the residues of the DC-SIGN-E-Glyco protein complex through citrus limonoids with its antiviral effect.

Rapid diagnosis of COVID-19 using disposal paper capacitive sensor.

Accurate and rapid detection and isolation become indispensable to restrict the spread of COVID-19. Since the start of COVID-19 pandemic in December 2019, many indisposal diagnostic tools are being developed incessantly.

A novel electrochemical interdigitated electrodes sensor for limonin quantification and reduction in citrus limetta juice.

Limonin, a highly oxygenated triterpene biomolecule of citrus fruits is responsible for delayed bitterness of its juice lowering consumer's acceptability.

Design and development of IDE sensor for naringin quantification in pomelo juice: An indicator of citrus maturity.

Maturity determination of pomelo fruits having health-benefiting attributes is an important issue to enhance the quality of harvesting. Here, an interdigitated electrode (IDE) based sensor is introduced to detect its maturity by determining the naringin content. The sensor was made by depositing amberlite IRA-400 as a sensing layer on IDE patterned PCB substrate at room temperature with hydrothermal and spin-coating techniques.

Variation in Phytochemical, Antioxidant and Volatile Composition of Pomelo Fruit ( (L.) Osbeck) during Seasonal Growth and Development.

Citrus fruits exhibit a high level of different phytoconstituents, of which the changes in the different parts of the fruit during ripening have not been thoroughly studied yet. Thus, in this study, we have investigated how different parts of pomelo fruit ( L.) are modified throughout the development of two consecutive growing seasons.

Meat quality assessment using Au patch electrode Ag-SnO/SiO/Si MIS capacitive gas sensor at room temperature.

An Au patch electrode Ag-SnO/SiO/Si MIS capacitive sensor equipped with a microcontroller was designed and developed to sense low concentration (ppb to ppm regime) of volatiles (NH, TMA, ethanol, and HS) generated from chicken meat spoilage at room temperature. The quality threshold or the acceptance limit for consumption of chicken meat samples stored at 4 °C, 15 °C and 25 °C using our proposed technique was found to be 105 h, 48 h, and 17 h respectively, highly correlated with TVB-N, TVC, pH and sensory evaluation analysis. When these well established standard methods (TVB-N, TVC and pH analysis) take many hours to complete the analysis involving many complicated steps, our fabricated sensor takes 55 sec to deliver sensing response reflecting the meat spoilage status.

All-optical tunable power splitter based on a surface plasmonic two-mode interference waveguide.

In this paper, we have introduced a surface plasmonic two-mode interference (SPTMI) coupler having a silicon core, GaAsInP side cladding, and silver top and bottom cladding as an optical power splitter. A wide range of tunability from the 50∶50 splitting ratio to 1∶99 is achieved by refractive index modulation of the GaAsInP cladding with application of varying optical pulse power. The coupling length of the SPTMI-based splitter is ∼11.

In this paper, we have proposed an ultra-compact surface plasmonic two-mode interference (SPTMI) coupler having a silicon core, silver upper and lower cladding, and GaAsInP left and right cladding for basic logic gate operations. By modulating the refractive index of the GaAsInP cladding with incidence of optical pulse energy, we have shown coupling characteristics depending on additional phase change ΔΦ(E) between the excited surface plasmon polariton modes propagating through the silicon core. By using applied optical pulse dependent coupling behavior of the proposed SPTMI device, the operations of NOT, AND, and OR logic gates are shown.

We have studied optical pulse-controlled coupling characteristics of the proposed device by using a simple mathematical model on the basis of sinusoidal modes.

Remuneration differences in the emerging economies of China and India.

Emerging economies by definition tend to be less dependent on expatriate skills and labour than lower-income countries, yet remuneration (pay plus benefits) differences between expatriate and local workers persist in them to some degree. According to relative deprivation theory, economic development paradoxically elevates the salience of relatively small gaps in remuneration. We therefore expected workers to report injustice and demotivation regarding relative remuneration, despite the closing of remuneration gaps between expatriate and local workers due to the economic development of recent years.
